摘要： The subject invention produces a water-absorbent resin by carrying out stationary polymerization of an ethylenically-unsaturated monomer containing acrylic acid and/or acrylate; cutting the resulting hydrous gelatinous polymer; and drying the hydrous gelatinous polymer which mainly contains angular particles having 6 smooth planes. The resulting water-absorbent resin particles are not aggregate, and can be efficiently dried. By coating at least a part of the surface of each of the particles with an adhesion block agent before, after, and/or at the time of cutting process, the adhesion preventing effect further increases.

摘要： A production method of a water-absorbent resin includes the steps of: obtaining a hydrogel by supplying monomer liquid to a reaction device so that the monomer liquid is polymerized; and detaching the hydrogel from the reaction device, wherein the reaction device's surface in contact with the monomer liquid at a position where polymerization occurs is made of a fluororesin having a melt viscosity of less than 1×108 poise at 380° C. On this account, it is possible to obtain a water-absorbent resin having less amounts of an extractable content with high productivity and it is possible to carry out continuous production for an extended period of time.
